  • File.Exists() returns false, but not in debug

    - by Tor Haugen
    I'm being completely confused here folks, My code throws an exception because File.Exists() returns false public override sealed TCargo ReadFile(string fileName) { if (!File.Exists(fileName)) { throw new ArgumentException("Provided file name does not exist", "fileName"); } Visual studio breaks at the throw statement, and I immediately check the value of File.Exists(fileName) in the immediate window. It returns true. When I drag the breakpoint back up to the if statement and execute it again, it throws again. fileName is an absolute path to a file. I'm not creating the file, nor writing to it (it's there all along). If I paste the path into the open dialog in Notepad, it reads the file without problems. The code is executing in a background worker. It's the only complicating factor I can think of. I am positive the file has not been opened already, either in the worker thread or elsewhere. What's going on here?

  • Drupal print module: controlling layout in PDF files?

    - by WhyKiki
    So I'm trying to fix the layout of the PDF files for a specific content type. I'm messing around in the tpl.php file and can't find a way to modify individual fields. There's just the massive $print['content'] variable that contains all of the page content. So, is there a way to access each field?

  • How to print 5 byte integer values?

    - by lost soul
    I've just started reading C and have a question about a macro. How can I print a 5 byte integer value (that happens to be defined in a macro)? For example: #define MAX 0xdeadbeaf12 int main(){ printf(" 0x %2x \n", MAX); } This code prints adbeaf12 but not deadbeaf12. How do I get all the bytes printed?

  • Debug the StackOverFlow exception

    - by BDotA
    When I run my C# program it throws an Stack Overflow exception in one of the methods on a DLL that I have a reference to it in my solution. but no debugging info is available to me because it says it is an stack overflow exception and no info is available. what are the next debugging steps that I should follow to understand what is going on and why ? thanks Edit: here is the code that stops at: static public Collection SortCollection(Collection oCollection, string sPropertyName, string sKeyPropertyName) { return SortCollection(oCollection, sPropertyName, sKeyPropertyName); }

  • Core Data - insertNewObjectForEntityForName debug

    - by Snow Crash
    I'm trying to figure out why insertNewObjectForEntityForName is not working. I assume it's something to do with my data model but can't be sure. Xcode does not report any errors nor does it crash. All I get is the first log statement output to the console. NSLog(@"Get here..."); Task *task = (Task *)[NSEntityDescription insertNewObjectForEntityForName:@"Task" inManagedObjectContext:insertionContext]; NSLog(@"but never get here..."); Any suggestions as to how I can work out what the problem is?

  • Print layout of C++ object with g++ compiler

    - by zaheer
    Is there a way to print the layout of a C++ object using the g++ compiler or any other means. A simplified example (assuming int takes 4 bytes) class A{ int a; }; class B:public A{ int b; } so the output would be A - 0 4 + a + B- 0 4 8 + A.a + b + It would be useful to understand the layout of objects (in my case virtual machine code). Thanks in advance. Regards, Zaheer

  • How to debug ConcurrentModificationException?

    - by Dani
    I encountered ConcurrentModificationException and by looking at it I can't see the reason why it's happening; the area throwing the exception and all the places modifying the collection are surrounded by synchronized (this.locks.get(id)) { ... } // locks is a HashMap<String, Object>; I tried to catch the the pesky thread but all I could nail (by setting a breakpoint in the exception) is that the throwing thread owns the monitor while the other thread (there are two threads in the program) sleeps. How should I proceed? What do you usually do when you encounter similar threading issues?

  • My HTML5 web app crashes and I have no clue how to debug

    - by Shouvik
    Hi All, I have written a word game using HTML5 canvas tag and a little bit of audio. I developed the application on the chrome web browser on a linux system. Recently during the testing phase it was tried on safari 5.0.3 on Mac and the webpage froze. Not just the canvas element, but interactive element on the page froze. I have at some times experienced this problem on google chrome when I was developing but since the console did not throw any error before this happened, I did not give it much credence. Now as per requirements I am supposed to support both chrome and safari but this dismal performance on safari has left me shocked and I cannot see what error can be thrown which might lead to such a situation. Worse yet the CPU usage on using this application peaks to 70-80percent on my 2yr old macbook running ubuntu... I can only but pity the person who uses mac to operate this app, which undoubtedly is a heavier OS. Could someone help me out with a place I can start with to find out what exactly is causing this issue. I have run profiles on this webapp on google chromes console and noticed that in the heap spanshot value increases steadily with the playing of the game, specifically (root) value which jumps up by 900 counts. Any help would be very appreciated! Thanks EDIT: I don't know if this helps, but I have noticed that even on refreshing the page after the app becomes unresponsive the page reloads and I am still not able to interact with the page elements but the tab scroll bar continues to work and I can see my application window completely. So to summaries the tab stops accepting any sort of user interaction inside the page. Edit2: Nop. It doesn't work still... The app crashes on double click on the canvas element. The console is not throwing any errors either! =/ I have noticed this problem is isolated only to safari!

  • Loop through Javascript array, print with string.

    - by Adam
    I have a simple array like: var myArr=["one","two","three"]; an I have a counting loop, which increases the value of var "i" by one. What I want to do is print the next value from the array each time the loop runs, next to a text string, like so: alert('value number '+myArr[i]+); But for some reason I can't get this to work. The following code works, so I'm assuming I'm not calling the counter right: alert('value number '+myArr[0]+);

  • Editing code in Visual Studio 2008 in debug mode

    - by user279521
    I am curious to know if there is a way to edit code in VS 2008 right when it has hit a breakpoint and I am walking thru the code... can I modify the code (such as the value in a variable or if my stepthrough line is about to hit an if statement ... can I modify the if statement....etc)? So far, I have to stop running VS, modify the code, then hit F5 and wait till the breakpoint is hit again.
